Inserting tabular values in the data block

Manually entering tabular values

NOTE
3-188
The following connection settings should be configured at WR_TAB:
LADDR = [specifies the logical address of the SIMATIC FM 458
application module]
RECNUM = [specifies the data set number for the read and write
channels. This must be identical with "Address stage1" at
the US connection of the TAB or TAB_D.]
DBNUM = [specifies the data block number]
In order to be able to transfer tabular values to a SIMATIC FM 458
application module, they must be available in a data block (DB). The DB
should be programmed on the control side.
There are two ways of generating a DB with the required tabular values:
• Generating a new DB in STEP7 and manually entering the tabular
values in the application "LAD/STL/CSF"
• Importing tabular values from an existing table (e.g. MS Excel) as
external source in STEP7
In this case, it involves the simplest method of providing tabular values in
a DB. It is realized by entering the initial (starting) and actual values of
the individual table values manually in a newly generated DB in the
application "LAD/STL/CSF". The steps required will now be explained.
The initial value is any value which can be defined for every tabular
value. It is only used if there is no actual value specified for the
associated tabular value.
The actual value is that value which is made available as tabular value
in the configured software. The required tabular values should be
specified here.
(1) Generating a new DB under STEP7
To start, a new DB should be generated under STEP7. In this case, the
"Blocks" folder is selected in the appropriate S7 program and in the
context-sensitive menu, the entry "Insert new object
selected.
The procedure is shown in the following diagram:
